In a random sample of six mobile devices, the mean repair cost was $80.00 and the standard deviation was $13.00. Assume the population is normally distributed and use a t-distribution to find the margin of error and construct a 99% confidence interval for the population mean. Interpret the results.CThe 99% confidence interval for the population mean u is(Round to two decimal places as needed.)The margin of error is $(Round to two decimal places as needed.)Interpret the results. Choose the correct answer below.O A. If a large sample of mobile devices are taken approximately 99% of them will have repair costs between the bounds of the confidence interval.OB. With 99% confidence, it can be said that the population mean repair cost is between the bounds of the confidence interval.O C. It can be said that 99% of mobile devices have a repair cost between the bounds of the confidence interval.O D. With 99% confidence, it can be said that the repair cost is between the bounds of the confidence interval.
